I posted last month regarding a friends bike I was working on, and where to start....I changed oil, coolant, battery, plugs, and after initial warmup everything seems to be fine (all fluid levels). However, the bike blows white smoke when given throttle, and idle is off every so often (misses). Does anyone wanna chime in? My thought is valve seals, burnt valve, or bottom end problems (no weird knocks either)...It may also need a stator? BTW this bike has 36k on the clock. If a video will help just let me know.
